[RFC v2 1/3] [gdb/symtab] Add find_symbol_for_pc_maybe_inline

[Tom de Vries <tdevries@suse.de>]

We have function find_symbol_for_pc:
...
find_symbol_for_pc (CORE_ADDR pc)
{
  return find_symbol_for_pc_sect (pc, find_pc_mapped_section (pc));
}
...
which uses some standard way of getting the section for the given pc.

Add a similar function find_symbol_for_pc_maybe_inline that calls
find_symbol_for_pc_sect_maybe_inline, and use it in jump_command.

Tested on x86_64-linux.
